What do you mean with "sector of particles"? Other particle types (which would get other names)? If they would have any similarity to electrons and protons, where are they?
The same particles? Well, apparentely they just couple this way.

Note that, as I said, there's a variety of such models, of which mirror matter is one. The basic idea remains that the symmetry group of nature contains two copies of weak isospin, SU(2)L and SU(2)R. The breaking scale for SU(2)R will be higher, there may be additional fermions, and the two Higgs sectors may or may not have similar structure.

Mirror matter goes a step beyond this, duplicating the entire symmetry group of the standard model, including the color group.
